DUMP-BODY PARTITION AND OPERATING MEANS THEREFOR.

Specificationy of Letters Patent.

Application led May 26, 1926.v Serial No. 384,303.

To all whom it may concer/n.:

Be it known that we, MOSES M. KAHN and FRANKLYN J. SILVA, citizens of the United States, residing at San IFrancisco, in the county of San Francisco, and Oakland, in the county of Alameda and State of California, respectively, have invented new and useful Improvements in Dump-Body Partitions and Operating AMeans Therefor, of which the following is a specification.

This invention relatesto dump body partitions and operating means therefor.

When emptying auto trucks or other transporting means equipped with dump bodies for transferring materials of *various kinds such as used in road construction and the like, it is often desirable that the contents of the body be dumped in several separate and equaLquantities for the purpose of mixing the different materials or for the purpose of l*distribution thereof. With this in view the present invention consists in employing .partitions for dump bodies and thus dividing the body into sev- -eral separate compartments of the same capacity. Also -the invention consists in mounting the partitions for swinging movement so as to permit the material to escape from the compartments when the bod is in its inclined or dumping position. eans are provided for locking the partitions in their closed or transverse position4 with relation to the body and also means for releasin saidpartitions for individually dumplng the contents of each compartment.

It is an object of the invention that the partitions are leasily detachable and that when removed the body will not be impaired in any way for use in other hauling purposes.

Another object of the inventionis to provide means for operating the partitions when dumping that one man can easily ma- The invention is illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of a truck having a dump body and showing in dotted lines the body in its inclined position for dumping.

Fig. 2 is a transverse section of the body.

Referring to the drawings more particularly--Fig 1 illustrates an auto truck equipped with a dump body which is generally indicated by A, rlhe body is of the conventional type having a tail gate 10 and sides 11. A front board closes the forward end of the body in` the usual manner. Transversely of the body and in equally spaced relation are mounted the partitions 12, in this instance three partitions, which ments. Of course it is to be understood Patented Apr. 26, 1921. l

Vdivide the body into four equal' compart- A ployed, depending upon` the capacity of each compartment desired. The partitions may be of any shape but preferably -as shown in Fig. 2. On each partition, longitudinally thereof, there is secured by rivets or the like an angle iron 18 and at one end thereo there is secured a trunnion 14, while on the other end of each angle iron there is likewise secured a trunnion 15, the trunnions 15 having an extended portion 16 which is squared as shown. The trunnions for each partition are j ournaled in a pair of bearings 17 whereby the partitions are permitted a swinging movement. The bearings are secured to the upper edges of the sides of the body by screw bolts 18 or the like, and, as is obvious, by taking out the screw bolts the partitions, as a whole, together with the trunnions and bearings can easily be lifted from the body. On each squared end portion of the trunnions 15 there is rigidly secured one end of an arm 19, the other ends of the arm 19 are bifurcated as at 20. On the same side of the dump body there are mounted controlling rods 22 one for each partition. These rods are journaled in angle irons 23 which are riveted or otherwise secured to the side of the body. The forward end of each rod 22 has secured thereon a member 24 which extends at right angles to the rod and adapted to project into `ing members 24 are bolted to the ends of thc rods so that they may be easily removed in case it is so desired.

A rear end portion 25 of each rod 22 is bent substantially at right angles to the rods and also these portions egitend at substan'- tially right angles to the locking members 24 on the forward ends of the rods. The portions 25 extend vertically when the lockmg members 24 are in locking position as illustrated in Fig. 1. On the end of each portion 25 there is formed a handle 26 and in order to hold these rods in their locking positions a suitable lock catch is provided for each rod as indicated at 27.

When the body ois raised to its inclined position and it is desired to dump the first or lowermost ofthe compartments, the tail gate, which is hingedly secured, is released and thus permitted to swing outwardly and allow the material in .said compartment to be dumped.

When another equal amount of material is desired the arm 19 holdin the lowermost partition is released which 1s done by first releasing the catch 27 on the rod associated with said arm, then grasping the handle 26 and swingingthe bent portion 25 outwardly and downwardly, which in turn rotates the rod and moves the locking member 24 out of the bifurcated end of the arm 19 and thus ermits the partition'to swing into its dotted ine position as shown in Fig. 1, and the contents in the second compartment allowed to dump. The remaining compartments are emptied in a like manner. Any of the rods may be turned and. operated by one man, without diiiculty.

It may also be ointed out that when it is desirable to use t e body without the partitions the partitions may be easil removed as before described, and the* ro s also removed by detaching the locking members 24,- releasing the catches 27 'and then withdrawing the rods from the angle irons in which they are mounted. Whenl all the paraphernalia has been removed it is to be observed that no openings in the body or projections are left to impair the same for its use in other purposes. The fact that no openings areleft in the body is a valuable feature in that if the body is desired to be Aused for hauling sand or the like, such openin would be a decided disadvantage.

ile we have shown the preferred form of our invention it will be understood that various changes in the combination, construction and arrangement of parts may be mad by those skilled in the art, without departing from the spirit of the invention as claimed.

Having thus described our invention, what we claim and desire tosecure by Letters Patent is:

1. In combination, a dump body adapted to be brought to an inclined position, partitions transversely of said body, means for mounting said partitions including a trunnion on each end of said partitions and bearing means therefor, an arm rigidly secured to one trunnion of each partition, means for locking said arms against movement, said means being adapted for individually releasing any of said arms and permit swinging movement thereof.

2. In combination, a dump body adapted to be brought to an inclined position, partitions transversely of said body, means for mounting said partitions including a trunnion on each end of said partitions and bearing means therefor, an arm rigidly secured to one trunnion of each partition, a rod rotatably mounted von the bodys side for each of said arms, coacting means on the one end of said rods and said arms whereby the arms are locked against swinging movement, said means being adapted to permit the arms to swing when sald rods are rotated to a predetermined point, and means on the other ends of said rods whereby they may be rotated.

3. In combination, a dump body adapted to be brought to an inclined position, partitions transversely o-f said body, means for mounting said partitions including a trunnion on each end of said partitions and bearing means therefor, an arm rigidly secured to one trunnion of each artition, a rod rotatably mounted on the odys s1de for each of said arms, coacting means on the one end of said rods and said arms whereby the arms are locked against swinging movement, said means being adapted to permit the arms to swl'n are rotated to a predetermined point, means on the other ends of said rods whereby they may be rotated, and means for holding said rods in theirvlocking position.

4. In combination, a dump body adapted to be brought to an inclined position, partitions transversely of said body, m'eans for mounting said partitions including a trunnion on each end of said partitions and bearing means therefor, an arm' rigidly secured to one trunnion of each partition, said arms having their opposite end bifurcated, a controllin rod rotatabl mounted on the outer side o? said body or each of sald arms, said rods each having a project/ing member when said rods extendin therefrom and adapted to en age v vagainst movement, and means on the other end of each of said rods whereby they may be individually and manually rotated to bring the projection out of the bifurcated end of the arm with which the rod is associated and permit a swinging movement of said arm.

5. In combination a dump body, partitions transversely of said body, means for mounting said partitions for swinging movement, a rod rotatably mounted on one side of said body for each partition, connecting means between said rods and partition whereby said partitions may be locked against swinging movement; said means being adapted to unlock the partitions and permit swinging movement thereof upon rotation of the rods.

6. In combination a dump body, partitions transversely of said body, means for mounting said partitions for swinging movement, a rod rotatably mounted on one side of said body for each partition, connecting means between said rodsI and partition whereby said partitions may be locked against swinging movement; said means being adapted to unlock the partitions and Vthat they-may be operated -of said body for each partition, connecting means' between said rods and partition whereby the partitions may be locked against swinging movement; said connecting means being adapted to unlock the partitions and permit swinging movement thereof upon rotation of the rods, and crank means on one end of each rod whereby they may be individually rotated.
